7202 Angular Contact Ball Bearings

7202 Angular Contact Ball Bearing | 7202C / 7202AC / 7202B

The 7202 angular contact ball bearing is a high-precision single-row rolling bearing engineered to support combined radial and axial loads. It delivers low friction, low noise and reliable high-speed stability, commonly used in precision transmission and light-medium industrial machinery. Available in 7202C, 7202AC and 7202B contact angle types, with bearing steel and stainless steel material options, this bearing ensures stable operation in dry, humid and mildly corrosive working environments.

Difference Between 7202C, 7202AC and 7202B

7202C (15° Contact Angle): Features a 15° contact angle with minimal friction loss and excellent high-speed performance. It maintains superior rotational precision with moderate axial load capacity, ideal for high-speed spindles and precision high-speed automation equipment.

7202AC (25° Contact Angle): Adopts a 25° contact angle with balanced radial and axial load resistance. With stable composite load performance and wide versatility, it serves as the universal cost-effective model for most standard precision machinery applications.

7202B (40° Contact Angle): Equipped with a 40° large contact angle for maximum axial load capacity. It stably bears heavy axial thrust at low and medium speeds, perfect for mechanical equipment with offset loads and heavy axial force.

Material Differences: Bearing Steel vs Stainless Steel

Bearing Steel (GCr15): GCr15 bearing steel is the mainstream standard material for 7202 series bearings. Professional heat treatment provides high hardness, outstanding wear resistance and strong anti-fatigue performance, guaranteeing long-term precise operation and durability in conventional dry industrial conditions.

Stainless Steel: Stainless steel 7202 bearings offer excellent rust-proof, oxidation and weak corrosion resistance. They effectively resist moisture, humid air and minor contamination, avoiding precision degradation and corrosion failure, suitable for food machinery, medical devices and high-humidity sanitary scenarios.
